FURROW-OPENING ATTAC-IMENT.

Application filed March 9, 1908.

To all whom it may concern.'

Be it known that I, OSCAR F. 'ORNDOFIL a citizen of the United States,residing at Harveys, in the county of Greene and State of Pennsylvania,have invented certain new and useful Improvements in Furrow-OpenerAttachments, of which the following is a full, clear, and exactspecification.

rlhe invention relates to furrow-opener at. tachments adapted and otherseeding machines and is particularly adapted for use on that class ofplanters and seeders provided with shoes of a colterlike formationadapted to open up the soil, and having a seed tube formed inconjunction therewith to deliver the seed. into the opening formed bythe shoe which precedes the point of delivery ofthe seed to the shoe.

Furrow-opening devices of the class to which the present inventionbelongs are used in conjunction with planters and the like of thecharacter' stated, for the purpose of opening up a furrow of more orless depth according to the manner in which the planter is adjusted andthereby enabling the shoe and the seed tube of the seeder to performtheir customary function of depositing the seed in the ground, but at amuch greater depth with respect to the surrounding earth since it isdesirable to plant the seed at the bottom of the Afurrow or at a greaterdepth below the surface of the surrounding soil than the ordinary depthto which the seed is inserted in the ground, without at the same timeincreasing the amount ol earth immediately over the seed.

The present invention is applicable to devices of the class describedprovided. with one or more rotating disks, usually two of such disks,one supported on each side of the shoe and so positioned as to throw theearth outwardly from the shoe as the shoe advances.

The primary object of the present invention is to provide an improveddevice of the character described that is simple, cheap and eflicientand at the same time enables the device to be readily attached to commonforms of planters or seeders of the class described.

A further object of the invention is to provide an improved device ofthe class described in which the means for supporting the axle whichcarries the disks and means for attaching the same to the seed tube andshoe of the planter or seeder is of a simpler and more ellicient formthan heretofore used, and

as it employs a much less number of parts, size or Specification ofLetters Patent.

being composed chiefly of a single casting, it

is therefore not only stronger and more dural ble in character but is atthe same time more economical to make in that there is less labor andmachine work necessary in fitting of parts in its manufacture.

To the attainment of these ends and the accomplishment of other new anduseful objects, as will appear, the invention consists in the featuresof novelty described in the speciication, pointed out more particularlyin the appended claims and illustrated in the accompanying drawings,forming a part of the specification.

ln the said drawings, Figure 1 is a view in side elevation ofthe deviceshowing the same attached to the seed tube and shoe of the common formof planter or seeder. ln this view one of the disks is removed todisclose the details of the construction of the parts embodying` theinvention. Fig. 2 is a plan view of the device as it appears in Fig. lbut showing both the disks in position. Fig. 3 is a detail sectionalview on line 3-3 of Fig. 1, showing the manner of attaching the deviceto the s ioe. Figs. l and 5 are detail views of parts appearing in Fig.3.

The shoe of an ordinary form of planter is indicated by the referencecharacter 1. 2 is the seed tube. The seed tube is shown rectangular incross section, which is a common form used on planters of the classdescribed, although it is common to construct these tubes of otherforms, as for example, nearly round in cross section or oval. 3 is anirregular shaped. member carrying the axle 4 on which the disks 5 and 6are journaled for rotation. The axle member It is preferably constructedof one continuous piece, of the form illustrated in Figs. 1 and 2. It ispreferably given the form 'llustrated and secured in the main body ofmember 3 by being cast therein at the time the member 3 is cast,although it will be apparent that it may be secured to the member in anyother suitable manner. The member 3 is provided with 2 spaced rearwardlyextending branches 7 and 8 which have their opposing or inner surfacesformed to converge inwardly towards the center of the member in themanner illustrated in Fig. 2, so that the adjacent faces of the brancheswill engage the face of the tube thus enabling these branches to find aposition of rest when placed in position on the seed tube whatever maybe the diameter of the tube and as the branches are of some thicknessthey will I other suitable manner, the ends of the axle 4 have extendedupright bearings against the tube. This feature is very desirable since1 these attachments are designed for use on all styles of planters andthe sizes of the various seed tubes of the same vary considerably indifferent planters. Member 3 is preferably provided with an integraldepending branch 9 which extends to the shoe, and for securing thisbranch to the shoe the clamping member 10 is provided and the same issecured to the branch 9 by any suitable means, as, for example, thethreaded bolt 11 passing through hole 12 in the member 10 and throughthe vertically elongated slot 13 in the depending branch 9. The slot 13permits the vertical adjustment of the supporting member 3 which isaccomplished by sliding the V-shaped bearing of the rearward] yextending branches along the forward vertical surfaceof the seed tube.The shoe 1 is usually formed wedge-shaped in cross section, being widerat the top than at any other part, as illustrated in 3, so that when itreceives the branch 9 and the clamping member 10, as illustrated in Fig.3, and the parts are tightened, the disk supporting member 3 will beheld firmly in relation to the shoe l and prevent it from movingupwardly in relation to the shoe. The clamping member 10 is providedwith a flange 10L adapted to bear against the branch 9 and serve as afulcrum in clamping the parts together. The work re uired to e done infurrow-openers of the ciaracter vto which the invention is shown appliedcauses the strains imparted to the supporting member by the disks to bein the u )ward and rearward directions. The V- aped socket formedbetween branches 7 and 8 is therefore admirably adapted to take therearward strains of the device since it linds its seat against the seedtube.

The branches 7 and 8 of the supporting member may be provided near theirrearward extremities with set screws 14 which, when tightened againstthe lateral walls of the seed tube, may serve as an additional means forsecuring the supporting member to the seed tube. These set screws may bedispensed with, if desired, in the exempliiication of the invention asshown since the means of attachment of the supporting member to the shoeand the support afforded between the member and the seed tube by reasonof the V-shaped socket affords ample means for holding the device in thedesired relation with the shoe and the seed tube.

The disks 5 and 6 are of the usual or any desired construction and maybe secured and held in position on the axle member 4 in any desiredmanner. In the form illustrated in the drawings, 15 is a hub or thimbleprol vided with ilange 15 by which, the disk is l secured in position byriveting or in any proJecting beyond the supporting member 3 enter thehub Y15. The inner ends of the hub 15 project beyond the disks toprovide a suitable inner bearing which they find by coming into contactwith suitable thimble washers 16. These washers 16 are preferablyremovable in order that they may be removed when worn and eitherreplaced or any lost motion taken up by inserting suitable washers overthe axle between the washers 16 and the member 3. The disks are held inposition on the ends of the axle by means of scrapers 17 which arepreferably secured by being bolted to the top surface of branches 7 and8 of the main supporting member 3 by bolts 18. The scrapers are of theusual form, extending upwardly over the rim of the disk and thencedownwardly and bearing against a portion of the exterior surfaceadjacent its cutting edge. They are preferably provided withlongitudinal slots 17 a, by which they may be adjustably secured bybolting to branches 7 and 8. It will be seen thatin holding the disks inposition these scrapers are only called upon to prevent their beingpulled off the axles when the device is not in operation in a normalmanner, since there is no tendency for the disks to work off the axlesas the thrust is all in the direction tending to force them against thethimble washers on the inner ends of the axles.

It will be apparent that by use of the construction. described anexceedingly simple device is provided and one which at the same time hasgreat strength in proportion to the amount of metal required. Also byreason of the fact that the parts or branches by which the axlesupporting member is attached to the shoe and seed pipe, are formedintegral or of a single casting, there is little liability of the devicegetting out of adjustment.
